Can Old Tires Be Exchanged for New Ones?

What Causes Severe Engine Shaking?

Severe engine shaking can be caused by the following reasons: 1. Engine misfire, which mainly refers to one or more cylinders in the engine not working properly. This is usually manifested as: the exhaust gas flow from the car has obvious intermittency, and the exhaust pipe shakes violently, making the engine's shaking clearly noticeable. 2. Deterioration or loosening of engine mounts. Engine mounts are rubber blocks placed between the engine and the car frame. Their function is to reduce the vibration and buffering during engine operation and to secure the engine in place. Once these mounts deteriorate or become loose, the engine's shaking will become abnormally severe. 3. Carbon buildup issues, including carbon deposits in the cylinders, throttle body, spark plugs, and intake system. When there is excessive carbon buildup inside the engine, the car's ignition energy, intake efficiency, and air-fuel mixture ratio will be affected, leading to unstable power output and shaking during idling and acceleration. 4. Fuel system failure, such as adding an incompatible fuel grade (for example, using 92 instead of 95), which reduces the car's power output and performance; or due to a blocked fuel tank vent, clogged fuel tank switch, fuel filter, or fuel lines between the tank and the carburetor, which cannot supply the required amount of fuel, resulting in a lean air-fuel mixture and engine shaking.

Can Chrome Trim Oxidation with White Spots Be Repaired?

Chrome trim oxidation with white spots cannot be repaired. The reason for the white spots is that the chrome plating layer on the trim has disappeared, mostly due to harsh driving conditions, prolonged exposure to rainwater erosion, or high salt content in the air. Chrome plating is commonly used for decoration around vehicle windows, door handles, front and rear bumpers, and the front grille, enhancing the vehicle's visual appeal. Modern car models incorporate a certain amount of chrome trim, which is difficult to replace. Removing the chrome trim separately may affect other vehicle components. Therefore, it is recommended to simply wipe the affected area, as white spots on chrome trim do not impact the vehicle's functionality.

Why does the Octavia shake severely at startup but stops when accelerating?

Severe shaking during startup in the Octavia may be caused by ignition system issues or unstable oil pressure. Ignition system issues: Check if the spark plugs have excessive carbon buildup and replace them if necessary. Inspect the working condition of the ignition coils, the overall performance of the ignition system, and the spark plug firing status. Unstable oil pressure: Check the oil pressure and replace components if needed. If you have already cleaned the engine carbon deposits, cleaned the throttle body, replaced the oil seals and spark plugs, but still experience body shaking at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor for any abnormalities.

How Many Kilometers Should a Sedan Drive Before Maintenance?

Different brands and models have varying requirements, but sedans generally need an oil change every 5,000 to 10,000 kilometers. Here are some relevant details: 1. In addition to mileage requirements, there is also a time requirement for maintenance intervals. Engine oil should not be used for more than one year. In summary, maintenance is required as soon as either the time or mileage indicator is met. 2. Besides mileage and time, another critical factor affecting oil change intervals is the type of oil used. Different oil types have different change cycles. For instance, mineral oil should be changed within 5,000 kilometers, semi-synthetic oil within 8,000 kilometers, and fully synthetic oil within 10,000 kilometers.
